These are the sample solutions for
problems <a href="soln2A.pdf"> 8.16, 8.17</a>
and <a href="soln2B.ps"> 8.18</a>. 
Note that there are several small discrepencies (like the problem numbers (again), major name (COSC instead of CS (Q8.16(a)), and the
years F. Wong taught (Q8.16(c))) between the supplied solutions
and the actual questions in your textbook. <BR>
